TagSustainable Airport Master Plan(280)

This February 2018 briefing presents an update to the Sustainable Airport Master Plan (SAMP) for Seattle-Tacoma International Airport, outlining both near-term improvement projects and a long-term development vision for the airport. The plan addresses existing conditions, development constraints, and key functional areas—including terminal, cargo, and displaced facilities—while also covering environmental review and stakeholder engagement processes. A phased approach guides how the airport intends to manage growth and infrastructure changes over time.

The Port of Seattle's February 2018 briefing updates the Commission on the Sustainable Airport Master Plan (SAMP), a long-range planning effort initiated in 2013 to identify facility improvements needed at Seattle-Tacoma International Airport over a 20-year horizon. The plan proposes a package of near-term projects—including 19 gates connected to a new terminal north of the existing complex—projected to meet capacity needs through 2027, while keeping the airport's current three-runway system in place. Public scoping for environmental review of these near-term projects was anticipated to begin in mid-to-late 2018.

The Des Moines Aviation Advisory Committee met on January 8, 2018 to discuss several airport-related concerns, including an update on the University of Washington Ultrafine Particle Study, a proposed interlocal agreement between neighboring cities to jointly respond to the Port of Seattle's Sustainable Airport Master Plan (SAMP), and a potential resolution advocating for a second airport. Community members and committee members also raised ongoing concerns about the health and noise impacts of Sea-Tac Airport on local residents.

This October 2017 Technical Memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines development alternatives for Seattle-Tacoma International Airport as part of its Sustainable Airport Master Plan. It covers a wide range of potential airport improvements, including airfield capacity enhancements, passenger terminal expansion, ground access and parking, air cargo facilities, and general aviation. The document evaluates options such as runway relocations, new taxiway configurations, and midfield terminal development to meet long-term aviation demand.

This report, prepared by Landrum & Brown for the Port of Seattle, documents baseline air quality conditions at Seattle-Tacoma International Airport as of 2016, as part of the Sustainable Airport Master Plan (SAMP) Environmental Review. It inventories emission sources across the airport—including aircraft operations, ground support equipment, and stationary sources like boilers and generators—and compares 2016 emission levels to those from 2014. The findings are intended to support future environmental planning and assessment of proposed airport development.
